Struct Startup 

pub struct Startup {
    pub opened_file: Option<PathBuf>,
}

Fired once per boot after Editor::boot returns. opened_file is the path (if any) the renderer’s post-boot seam captured from the boot Document before it moved into Editor::boot (which consumes it).

Examples

use lattice_mode::Startup;
use lattice_runtime::EventBus;

let bus = EventBus::new();
let (tx, mut rx) = tokio::sync::mpsc::unbounded_channel();
bus.subscribe_typed::<Startup>(tx); // e.g. from a subsystem's `install`
bus.publish_typed(Startup { opened_file: None }); // the renderer, after boot
assert!(rx.try_recv().unwrap().opened_file.is_none()); // no file: show a dashboard

Fields

opened_file: Option<PathBuf>

The file named on the command line, or None when the editor started without one.

Trait Implementations

impl Clone for Startup

fn clone(&self) -> Startup

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Startup

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Event for Startup

fn event_type_id(&self) -> EventTypeId

The type-id under which this event is registered. Implementors typically delegate to a static to avoid re-allocating the metadata on every call. The macro register_event! generates this for you.
